PERFORMANCE & DURABILITY
1. Will it work on cloudy, rainy days or when there is no sunlight?
The Sun Lizard needs some sunlight to work. Make sure that your
custom system allows to bring in the air from the collectors when
there is a level of heat in the collectors. Otherwise, drawing
air through the collectors for heating when there is no sunlight
will reverse the effect and cool the incoming air.
2. Can it store the heat collected during the day for use at night?
No. The Sun Lizard uses your building as a thermal store but cannot
store the heat for night use.
3. What if I don’t have that much sun on my roof?
The Sun Lizard needs to get a minimum amount of sunlight to work,
generally at least 4-5 hours on average a day. If you don’t
get this minimum amount, then the Sun Lizard may not work for you.
See the Quick Suitability Assessment for more details
4. How long will it last?
The solar thermal collectors will last in excess of 25 years. See
our Sun Lizard Australia Warranty for more details
5. Does it heat water or air?
The Sun Lizard products are designed to heat and cool air only. They
are extremely efficient at this, but will not work with water. Solar
Hot Water systems are available from different manufacturers
6. Will it rust if I live near salty water?
All metals will eventually deteriorate in salty conditions. We have
used materials that are resistant to seaside installations, but you
should check with your builder or a local plumber to ensure that
it will survive your local conditions.
7. Is it cyclone proof? Will it blow off my roof?
The Sun Lizard is extremely robust and we have had cars drive over
them with no damage. But they need to be securely fixed to the roof
structure in areas that are prone to severe weather conditions. This
is the responsibility of the installer.
8. Do I need to maintain it?
There are no specific maintenance requirements. However, from time
to time you should check that the glass is cleaned of any severe
dirt or dust.
FUNCTIONALITY & AESTHETICS
9. Can I integrate it with my current ducted system?
Yes you can integrate it. However you will need to plan your integration
carefully. It is because the collectors are on the roof and at night,
unless you have a system of gates to stop hot air from your existing
heating system going out to the collectors, you will end up losing
heat through them. Some form of smart temperature sensors and controls
needs to be linked to motorised gates to make the system work effectively.
Otherwise we recommend you have the heat collectors setup as a standalone
10. Will it look too obtrusive on my roof?
In most cases you will not see the Sun Lizard on your roof. However
if you need to use a frame or if your home is down a hill and the
roof can be seen, then the Sun Lizard will be seen on your roof.
But the Sun Lizard is a low profile box and is unobtrusive on most
roofs. Click here for showcases.
11. What if my building is bigger than what the unit can do? Can
I put more units in, hook them up in series?
If you have worked through the Suitability Assessment and the space
you want to heat is bigger than the recommended size, then you can
add any number of combinations. It is also possible to create custom
systems if you have a specific application such as a large community
building or school. The Sun Lizards can be hooked up in arrays of
parallel or in series units to achieve higher temperatures or airflow
12. What about noise?
The solar heat collectors do not have any fans so do not make any
noise. You will need to add your own fans and controls so can choose
these for low noise..
13. Can I install it on a wall instead of my roof?
Yes it is possible to install on a north facing wall.
14. What about the air quality? Where does the air come from? Can
I take it from my ceiling cavity?
In designing your solar heating system you need to make this assessment.
Generally we suggest that unlike some other heating systems that
draw air from the ceiling cavity you draw air from inside your building
or from outside, where it is reasonably clean. The air in the ceiling
cavity of many homes is very dusty and may have contaminants from
birds, rodents and fibreglass or asbestos. We don’t recommend
using air from this space for those reasons.
15. Does the Sun Lizard
The Sun Lizard does not change the humidity in the building. However,
by keeping the building temperature at a comfortable level, not
too cold and providing air movement, it stops the build up of damp
16. Are there any health benefits in exposing the air to high heat
While no scientific study has been done on the Sun Lizard in regard
to this, it is known that exposure to UV and high temperatures will
reduce the build up of bacteria, virus, mould and fungi. Ventilation
and air movement are also important in reducing damp areas that allow
the growth of mould and fungi in buildings.
INSTALLATION & DISTRIBUTION
17. What if I can’t find a distributor in the area that I live?
What if I can’t find someone to install the Sun Lizard for
It is quite easy to install and we provide an installation guide
on our website. If you choose to engage a local plumber we do provide
all the installation components. We would also be happy to work with
your local plumber and offer step by step instructions on how to
install a Sun Lizard.
18. How can I assess the suitability of the Sun Lizard in my home
or building? Can I get someone to do a site inspection?
You can fill in the Suitability Self Assessment Test and this will
give you a good picture of your homes suitability. If you are confident
the Sun Lizard is going to work and need a quote for installation,
we can try to help you find an installer. Also check out the distributor
list to find someone close to you who may be able to offer some good
advice. Note however, that for custom systems, you should consult
with a number of people (engineers and heating specialists) to ensure
your design will work and is effective as well as being safely installed
on your building.
19. Can I do it myself or get my friend to install the Sun Lizard
on to my roof?
We recommend using a qualified tradesman to do the installation so
it is done professionally. However it is a relatively simple installation
and can be done by yourself. Please check any local requirements
or laws that need a qualified tradesman.
20. If I have a cathedral ceiling or a flat roof or deck roof will
it still work in my home or building?
While it is a little more difficult with this type of roof, it only
requires a little planning to make it work just as effectively. To
avoid having long lengths of pipe or ducting on the roof, you need
to locate the inlet and outlet ducts close to the point the ducting
is going to go inside the building. Any ducting on the roof needs
to be weatherproof and insulated to avoid heat loss. See the installation
guide for more details.
21. What if I have no cavity in my walls, can it still be ducted?
Yes you can run box duct on the outside of the wall, or ducting inside
a cupboard or wardrobe. It is just a personal preference regarding
aesthetics and location, but almost always there is a place to run
22. What if I have no roof space, can I still use one?
The Sun Lizard is designed to sit on the roof. However, it is possible
to place the Sun Lizard on a wall or even on the ground if no other
suitable location can be found. There are minor issues with other
alternatives, but they can work.
23. I want to become a distributor or installer, how do I get involved?
We are always looking for enthusiastic distributors and qualified
tradespeople who are keen to promote sustainable products. Contact
us with your interest and experience. We provide product information
and installation training sessions around Australia so will advise
you when one will occur in your area.
24. What if I can’t see a working display
of a Sun Lizard in the area that I live in? Where can I find working
See our showcase page for examples of installed Sun Lizards.
Most of our installations are invisible from the ground so are not
suitable for viewing. We also respect the privacy of our customers
and unless volunteered, we do not approach existing customers asking
for them to talk to prospective customers. However, if you tell us
which area you are in, we will try to find the location of a display
unit or installed unit that that the customer is happy to show off
25. What do other people think about your product? What are some
of the best things about the Sun Lizard people comment on? Why would
I want to by a Sun Lizard?
The most common thing people say is “What a fantastic idea” and “Why
hasn’t it been done before?” Existing customers say
they feel much more comfortable and their energy bills have gone
down. Many customers buy a Sun Lizard because they want to reduce
their energy consumption and bills, but also to reduce greenhouse
gas emissions and global warming.
COST, ORDERING, PURCHASING & SHIPPING QUESTIONS
26. What is the cost of the Sun Lizard Solar heat Collector?
The cost of a single collector Sun Lizard unit is $950.
27. How much does it cost to install on my home?
Installation costs can’t be predicted for a custom designed
system, but for our other products such as the Climate Control System
it can range from about $200 to $1200 depending on the structure
of the house and whether you choose to install it yourself or arrange
for an installer or plumber to make the installation
28. How much is the cost of delivering a Sun Lizard to my home or
Depending on where you are in Australia it will vary from $40 to
around $250 per collector.
29. Are there any rebates or subsidies available for the Sun Lizard?
Currently there are no rebates or other subsidies. From time to time
various government agencies have grants for installing energy efficient
products and the Sun Lizard qualifies for these. We are presently
working through the process of getting rebates and would appreciate
your support. Please click here to sign your name to a petition to
get rebates for solar heating products.
30. What is the payback period?
Payback on the Sun Lizard depends on a number of factors. These include
your existing heating and cooling system (gas/electric/reverse cycle)
and your home (how energy efficient is it). It also depends on whether
you are retrofitting and have therefore already paid for your existing
heating and cooling system or are putting in a new system, in which
case you can design and integrate the Sun Lizard and another much
smaller system much better into your home. In this case you save
money immediately on your up front costs. Typically payback is around
3-10 years. Please see our Comparison Tables for further information.
